Definitions
- an electrical flushing device for a toilet wherein the toilet cannot be repeatedly flushed and cannot be flushed at all if the water level is dangerously high in the bowl.
- Another object of the present invention is to provide a device wherein all controls including the electrodes which actuate the toilet protective device are located in such a manner that they cannot be reached or defeated by an inmate.
- Still a further object of the invention is to provide an electrical flushing device which is fail-safe in that the protective feature is not dependent upon the electrical supply so that if the electrical supply fails, the toilet cannot be flushed.
- Still another object of the present invention is to provide an alarm system for a toilet so that in case the level of water in a toilet bowl reaches a high level, an alarm will be sounded and also means can be provided to rapidly determine which toilet is causing the difficulty.
- FIG. 1 is a side view, partly in section of a toilet embodying the present invention.
- FIG. 2 is an enlarged sectional view showing the location of the sensing electrode.
- FIG. 3 is a wiring diagram of the toilet flushing device.
- the electrical flushing toilet of the present invention includes the usual bowl generally designated 5 mounted on a cabinet 7.
- the toilet is provided with a water supply 9 which leads to a flushing valve 11 and the outlet 13 of the valve goes to the main flushing line 15 which discharges the main body of water into the rim 17 of the bowl where it enters through holes 19. A portion of the water passes through blow-out line 21 to initiate the syphon action. Waste leaves the bowl through line 23.
- flush valve 11 would normally be actuated by a mechanical handle, not illustrated, mounted thereon.
- an electrical actuator 25 for valve 11 is provided and current is supplied to the actuator through the power supply lines 27 and 29 through push-button switch 31.
- the power supply lines also go to the primary 35 of the induction relay generally designated 33.
- the induction relay is well known to those skilled in the art and consists of a transformer having a primary 35 and a secondary 37 with an armature 39 which is actuated only when current flows in secondary 37. In other words, if the leads to the secondary are open, the armature is not drawn in.
- Contacts 41 of the relay are normally closed while contacts 42 are normally open. Contacts 41 are in series with line 29 leading to actuator 25.
- One side of the secondary 37 is connected by means of wire 43 to the insulated electrode 47 located far back in line 15. The other side is grounded through line 45; it could be connected to the outside of pipe 15 by ground clamp 49.
- the induction relay was a B/W type R (made by B/W Controls, Inc.) enclosed in an NEMA 1 enclosure.
- the primary coil was 115 volts while the secondary coil was 360 volts for use in potable water systems. Since the secondary 37 operates at such a high voltage, it is obvious that only a slight conductivity of the water in pipe 15 is required to close the circuit.
- the induction relay 33 is fitted with a normally open contact 42 connected through a time delay relay 55 in series with the AC line and can be used to actuate either a light 59 or an audible warning device 61, or both.
- the light 59 might be located in the warden's office so that officials will be instantly aware of the exact cell location of attempted flooding.
- the time-delay relay 55 should have a time delay which is longer than the time which is normally required for the line 15 to drain during a normal flushing cycle.
- the induction relay 33 could be replaced with an ordinary step-up transformer with a solenoid wired in the secondary to actuate the armature of a relay or with a solid state device.
- Two insulated electrodes could be employed rather than the single electrode operated against ground which is, of course, necessary in the case of plastic piping.
